  1. Cheap chinese stuff I have bought that worked out really well:


    The EV-peak C1 lipo charger. Great charger. Costs roughly the same as am imax b6 but has more charging power and most importantly, a user can set a target voltage for charging. For example, I have a 12S ebike pack and maybe today I only want to charge the pack to 4.0v per cell. Easy, go into the charger and set it like that. The imax b6 is not end-voltage adjustable by the user.


    My cheapo plastic calipers for $2. Used them a bunch of times. 


    My Ming he DC-DC converters I use to bulk charge my ebike batteries. 


    A couple of screwdriver sets. I think I lost the bits before the set wore out. 


    Any connectors and silicone wire comes from china and has always worked out great. 


    My ebike hub motor worked great until I sent 96v through it at 40A and it died, so no surprise there. 


    I have one of those cheap IR temperature guns that seems to do the job. I'm not sure how accurate it is, but ballpark numbers are better than nothing. 


    I just bought this today with the mail in rebate cards I got back from newegg:




    the reviews say it's pretty good. It's not a weller but I don't need it to be one. This station will probably be used mostly for 18-14AWG wire anyway. The hot air portion of the station is going to be used to replace a burned out surface mount MOSFET on one of my imax B6's that broke some time ago.
